SPRING KNOB-LOCK.

Specification of Letters Patent.

Patented Dec. 30, 1919.

Application filed May 8, 1919. Serial No. 295,547.

To all whom it may concern:

Be it known that we, HYMAN Mnrnznn and LOUIS KARRON, citizens of the United States, and residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Spring Knob-Locks, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to what are known as spring knob locks for use in connection with handbags, pocketbooks and similar articles, and the invention comprises both the article or articles and the method of making the same; and the object of the invention is to improve and simplify the construction and operation of devices of this class and to make the same more strong and durable, while at the same time rendering the manufacture thereof more economical.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of our improvement are designated by suitable reference characters in each of the views, and in which Fi ure 1 is a side View of a handbag frame provlded with our improved knob lock de vice or devices, part of the construction being broken away;

Fig. 2 an inside view thereof looking in the direction of the arrow 2 of Fig. 1;

Fig. 3 a side View of a blank from which one of our improved knob locks is formed;

Fig. 4 a side view of a complete knob lock device formed from said blank;

Fig. 5 a cross sectional view on the line 5-5 of Fig. 4c; and,

Fig. 6 a view similar to Fig. 1 but showing only one jaw member of the frame and showing it on an enlarged scale.

In the drawing forming part of this specification, we have shown at a in Fig. 1, the frame of an ordinary handbag, pocketbook or similar article, and said frame consists of two jaw members a which are U-shaped in cross section, and which are connected at a in the usual manner.

We have also shown at b in Fig. 1 our improved knob lock which comprises two separate similar parts a, both. of which are exactly alike, and both of which are formed from a blank 0 of sheet metal shown in Fig. 3, said blank being approximately L- shaped in form and one arm thereof being provided with a circular head 0 and the other arm thereof being provided with proj ecting tongues 0 the body of the blank, the head 0 and the tongues 0 being all in the same plane.

In forming the knob lock devices from the blank 0 the head portion 0 thereof is stamped or formed into a cup-shaped knob c which opens downwardly or inwardly, and this operation completes the knob lock attachments before they are applied to the jaws (0 In applying the knob lock devices to the jaws a of the frame, said jaws are provided centrally of the top thereof with apertures a through which the tongues 0* of the knob lock devices are passed, and after said tongues have been passed through said apertures, the said tongues are split as shown in Fig. 6, and the side portions thereof, thus formed, are forced outwardly as shown at c in Figs. 1, 2 and 6, which operation is performed by a suitable die device, and this operation firmly connects the knob lock devices with the jaws of the frame as will be read ily understood, and said knob lock devices cannot be detached from the frame without breaking or destroying either or both of said knob lock devices or the frame.

It will be understood that the bag, or the material thereof, may be connected with the frame in the usual or any desired manner, and while the frame shown is of the usual yoke-shaped form, our invention is not limited to the exact shape of the frame, nor to the dimensions thereof, nor to any dimensions of the bag or pocketbook to which it may be applied, and various changes in and modifications of the details of construction herein shown and described may be made, within the scope of the appended claims, without departing from the spirit of our invention or sacrificing its advantages.

Having fully described our invention, what we claim as new and desire to secure by Letters Patent, is

1. The herein described method of making knob lock devices for handbags, pocketbooks and the like, which consists in cutting a blank of approximately L-shaped form from a sheet of metal providing one arm of the said blank with a circular head and the other with projecting tongues and forming said head into a cup-shaped knob.

2. A knob lock device for use in connection with handbags and the like, said device being stamped from sheet metal and comprising a flatbody portion provided at one end with an arm which projects at right angles thereto and is provided With a cupshaped knob which opens inwardly and the body portion being provided on the side edge thereof opposite said arm with proectlng tongues.

. In testimony that we olalni the forego- HYMAN MELTZYNER. LOUIS, KARRON.
